-When contributing to Monkeytype, it's good to know our best practices, tips, and tricks. First, Monkeytype is written in ~~JavaScript~~ TypeScript, CSS, and HTML (in order of language usage within the project); thus, we assume you are comfortable in these languages or have basic knowledge of them. Our backend is in NodeJS and we use MongoDB to store our user data. Firebase is used for authentication. Furthermore, we use Prettier to format our code.
